EDWARD TELLESON, OF BINGHAB'TON, YORK.

WHEEL Moniv'r..

' city ofjBinghamton, county of Broome, and

tate or" NewA York, have invented new and Vuseful'Improvements in Wheel Mounts, of

. which the :tollowingis a speciication, reference being had to the accompanying drawings. Y i

The present invention relates to improvements on wheel mounts for trolley heads, and is an improvement upon my invention patented vvto me under date of J une 2, 1914',

by Patent Number'1,098,464. That patent rovers a removable and rotatable trolley liead.V It is the purpose of this invention to supply specific resilient means for maintaining the trolley wheel in normal parallelism with the trolley wire, while at the saine time permitting the trolley wheel to rotate slightly either to the right or left when rounding curves.

It is a further purposeV to provide aV U- shaped metallic spring member or conductor interposed over the wheel axle or shaft, and pressing against and extended between the ends oi the hub of the wheel and the trolley head proper, as a means for more posiively conveying the electric current.

It is afurther purpose of the invention to pro-vide a tongue extended from the trolley pole upwardly over the trolley wheel and projected toward the trolleywire as means for both preventing the crosspole wires from becoming locked in front of the trolley head 'when the latter accidentally leaves the trolley wire.

In the'drawingsn-` Fig. 1 is a sectional side elevation showing my improverments;`

Fig-2, a rear elevation of the same;

Fig. 3, a front elevation;

Fig. l, a top plan view; Y

Fig. 5, a perspective detail of the U- shaped metallic spring member;

Fig. 6 is a detail showing how the tongu element of the device operates 'to prevent crosspole wires from catching in -ront of the trolley wheel.

Referring more particularly to the draw ings. in connection with the rotatable trolley headv l described and claimed in my aforesaid patent, l provide a hook 2 at the `forward side thereof, which may be bolted, soldered, or 'otherwise rigidly secured in placa-and a complementary hook 3 similarly Amnicatin mea Ap'n 2e, 191e.' Yserial No. 292,856. Y

secured Vat the rear side ot the goose-neck shaped end 50i the trolley pole 1. Between 4 the two hooks 2 and 3, I mount the retractile coil spring 6, so tensioned as to'normally hold thesaid .rotatable Vtrolley head e in a straiihtaway 'forward position, and so that the planeot'the trolley wheel 9 will normally stand in parallelism with the trolley wire 10. At the top of the upper elbow 11 of the goose-neer shaped end 5, 1 rigidly mount the metallic tongue 7 by means `of screws, such as 8, or otherwis This tongue 7 projects upvardly and backwardly, so as to overhang the periphery oi the trolley wheel 9'immediately belowthe trolley wire 10, and the tongue 7 is conveXed-outwardly as shown at so as to facilitate its -function, which is to prevent the cross wire 12 from being caught, should the trolley wheel 9 leave the. trolley wire V10. In' such event, the convexed end 22 of the tongue 7 would catch the crosspole wire 12 upon the upward movement of the trolley wheel 9, and would prevent the said crosspolc wire from becoming engaged between the trolley wheel 9 and the elbow 11, and so that the entire apparatus would be free for pulling downward and resetting upon the trolley wire 10 in usual manner.

I further provide a flat U-shaped metallic spring member 13, which is made of flat spring metal and is provided with oppositely positioned shaft holes le, one at the upper end oft each of the arms or" said member 13, through which the axle or shaft 15 is passed when the trolley wheel 9 is mounted in position. This Ushaped member 13 follows in general the inner contour of the fork 16 within which the trolley wheel is mounted in usual manner, and the :toot 17 of this U- shaped member passes underneaththe washer 18 and is secured in place by the shank 19, which passes upwardly from the base of the trolley head 4 through the hole 20 formed through the foot 17 of the U- shaped member. A cotter pinV 21 passes through the washer 18 and the shank 19, and locks the U-shaped member in place as well as securing the trolley head t in rotatable position. rThis method of mounting the trolley head 4.- in connection with the end oi" the trolleypole is described in my aforesaid patent, and nothing new is claimed herein over said patent in respect of the general method of mounting.

The improvements claimed relate to the U-shaped member 13, the retractile spring 6 and its mounting, the goose neck 5 at the upper end of the trolley pole 1, and the projecting` tongue 7. The upper arms of the U-shaped metallic spring member 13 are c adapted to set closely and snugly against f the outer ends 21 of thehubof the trolley wheel 9, and the foot o1- tlie same Ushaped member being; in snug contact Withthe` 10 trolley: head 4C, an additional and positive means for conveying` the electric current from the trolley Wire through the trolleyV Wheel Aand trolleypole is thus provided.

ln constant use, the bearings and the ends Y of the hub 'of the trolley Wheel wouldV becomep Worn so that gaps'would be created Vbetween Vthe ends 21 of the hub of the trolley y wheel, and the arms ofthe forkiethus inf Y tongue for the purposesof the invention.

.In operation, the spring 6 normally holds lthe trolley Wheel 9 in straight-away position, at the same time permitting it to de- 'wheelf Heet to eithersside inrounding curves. V'lrhe tongue 7 prevents the locking'of the crosspole Wires 12 in front ofthe trolley Wheel 9 in case of displacement of the trolley Wheelv Vfrom the trolley Wire 10, While the U-shaped metallic spring meinber- 13Y facilitates the passage of thev electric current vfrom the trolley wireto and through the trolley pole. TWhile VI' have herein described a certain specific manner and methodofconstructinge and assembling v4the elements fof jmy inyen-V.- Y. tion, it is kunderstood that Ipmayyaryffrom from the spirit of my invention, so ,as best the Asame` in Vminor details, not departing-Y toconstructa practical 'device for the pur-V Y pose intended, asl defined intheap'pendedA claim.
